What is Volume in science?

Volume is the quantity of three-dimensional space occupied by a liquid, solid, or gas. Although many other units exist (like gallons, ounces and teaspoons), the International System of Units (SI) standard unit of volume is the cubic meter (m3) for solids and milliliters (mL) for irregular solids and liquids.

Calculating Volume of regular solids

For three-dimensional shapes like cubes and rectangular prisms, we can find the volume by measuring its dimensions; using a unit of length (e.g. meters or centimeters) and then applying the formula L x W x H to determine its volume. The unit of measurement would be the cubic value of the unit used for length.

Multiple Choice

Kayla found two boxes in her storeroom. Box 1 has the dimensions 6 x 2 x 3. Box 2 has the dimensions 2 x 3 x 6. Which box holds more baseballs?

• Box 1

• Box 2

• Neither, they both hold the same amount.

Calculating Volume of liquids

To measure the volume of a liquid, it can be poured into a graduated measuring vessel of some kind. Its volume can then be seen by looking at the graduations on the side of the measuring vessel. Volume of a liquid is usually expressed in terms of milliliters (mL), or submultiples of a liter (L).

Calculating Volume of liquids

Measuring liquid volume requires a certain method. Vessels used to measure the volume of a liquid should always be placed on a flat surface. The surface of liquids have a tendency to form a curve (called the meniscus) which should be read at the lowest level of the surface of the liquid, making sure that the eye is level with the surface of the liquid.

• 43.0 mL
• 44.0 mL

Multiple Choice

What is the volume of the liquid in the picture

Calculating volume of irregular solids

 We can find the volume of an irregular solid object using a method called fluid displacement. Step 1 is to fill the cylinder with enough water to immerse the object and measure the volume. Next you would add the object to the water until it is totally submerged and measure the new volume of the water. Subtract the first reading from the second to get the volume, in milliliters, of the object.

Multiple Choice

Which of the following is NOT a step in finding the volume of an irregular shaped solid object?

• Measure and record an amount of water in a graduated cylinder

• Add the object to a graduate cylinder with a known amount of water and record the new water level

• Use the formula to multiply the length by the width by the height

• Subtract the water level of the with the object in it from the amount of water before the object was introduced

Multiple Choice
